ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 605,669, dated June 14,1898. Application het June '29, 1897. serial No. 642,871. (No model.)

To @ZZ whom it may concerm' Be it known that I, SIGMUND V. HUBER, a citizen of the United States, residingI at Youngstown, in the county of Mahoning and State of Ohio, have invented or discovered certain new and useful Improvements in Rolling-Mills, of which improvements the following is a specification.

The invention described herein relates to certain improvements in the construction and operation of feed-tables for atrain of two or more three-high mills arrangedin a common line of feed, and has for its object a construction of vtable and operating mechanism whereby it is possible t`o receive the article from between the lower and middle or the upper and middle rolls of one stand and to feed it between the lower andl middle or the upper and middle rolls of the next stand.

The invention is hereinafter more fully described and `claimed.

In the accompanying drawings, forming a part of this specification, Figure l is a view in elevation of two stands of rolls arranged in a common line of feed and having my improved feed mechanismarranged between them. Fig. 2 is a View in elevation, on an enlarged scale, of a portion of the mill shown in- Fig. land also of the front of one of the end feed-tables. Fig. 2 is a similar view, being a continuationof Fig. 2 and showing the lremaining portion of the intermediate feed-table and also `the end feed-table. Figs. 3 and 3a are plan views illustrating my invention, a portion of the mill being shown in Fig. 3 and the remaining portion in Fig. 3a; and Fig. 4L is a side elevation showing'two stands of rolls with a floating table.

In the practice of my invention the stands of rolls A B, dac., are arranged on suitable' foundations in line with each other, as shown in Figs. 3 and 3a. At the ends of the mill are located the tables C and D, which'are preferably similar in construction and operation. These tables consist of a 'frame 1, having a series of rollers 2 mounted thereon and positively driven in the usual or any suit able manner. At their outer ends these tables are pivotally mounted upon blocks 3, as clearly shown in Figs. 2 and 2a. The intermediate tables E and F are similar in construction and consist of frames 4L, provided with positively-driven feed-rolls 5. ner or adjacent ends of the tables E and F are pivotally mounted and by preference upon a common pivot suitably supported on foundation-blocks 6. The tables O and E and lD and F are operated in pairs and simultaneously-that is to say, when the table C is raised to feed or receive an article to or from the upper and middle rolls of the stand Athe table E should be shifted to a corresponding position. The tables D and F are similarly operated'.

As it is sometimes customary to feed an article from the upper and middle rolls of one stand, as A, to the middle and lower rolls of the next adjacent stand, as B, I have shown the tables in connection with an operating mechanism adapted for effecting such adjustment of the tables, but do not wish to limit myself to such a mechanism or to such a mode of operation. y

The table-shifting mechanism consists of a fluid-pressure engine 7, having its piston-rod 8 connected to bars 9, which extend in both directions under the tables E and F and are connected under the tables to arms 10, secured upon shafts 11, which also have secured thereto arms 12, having their outer ends connected by links 13 to the frames 4 of the tables at or near their outer free ends. While the rods 9 may also extend under the tables O and D, it is preferred to connect the-arms 10 to arms 14 by independent rods 15. These arms 14 are secured on shafts 16, mounted in suitable bearings under the tables O and D, and to the shafts 16 are also secured arms 17, having their outer ends connected by links 18 to th frame l of the tables O and D.

By reference to Figs. 2 and 2a it will be seen that the table-lifting mechanism of the fables Gand E is so constructed and arranged that equal and similar vertical movements are imparted to both tables.

By reference to Fig. 2a it will be seen that the tables E and F are similarly operated, and by comparison of Figs. 2 and 2* it will be seen that'the tables D and F are operated reversely tothe tables C and E-that is to say, when the tables C and E are raised the tables D-and F are lowered. I Vdo not, however,

limit myself to this reverse Yoperation of the tables,nor`to the operation of such tables by The in- IOO a common motor. On each side of the several tables and adjacent to their free ends are arranged guides lt) for steadying the tables while being shifted in the manner described.

\Vhile it is preferred to operate all the feedrollers by a single reversing-engine, it will be readily understood by those skilled in the art that two or more engines may be employed for that purpose.

In lieu of forming the intermediate feedtable in two or more sections, as shown in Figs. l, Q, and 3, it may be made continuous, as shown in Fig. i, each end being connected to suitable mechanism, such as that used with the sectional table for raising the outer ends of the table. In lieu of simultaneously operating' both ends by a common motor two independent motors, as 7 and 7b, having suitable connections to the table at or near its ends, may be employed for its adjustment. In some cases two independent motors for operating the tables are preferable as affording greater flexibility in the manner of operating the mill. When using a floating table, as in Fig. 4, the journal of one of the fixed rollers is extended and is connected by a flexible train of gearing, as shown in Fig. -l-, to a suitable driving mechanism.

Itis characteristic of my improvement that an article can he fed along between the lower and middle rolls of the several stands, or its direction can be changed between adjacent stands so as to pass from the lower and middle rolls of one stand to the upper and middle rolls of the next stand, and vice versa.

It willbe readily understood by those skilled in the art that many changes and modifications may be lnade in the construction and arrangement of the several parts, and such changes or modifications as maybe held as equivalents of the parts specifically described and shown are expressly included as a part of my invention.

I claim herein as my invention- 1. In a rolling-mill plant, the combination of two or lnore stands of rolls arranged in, or approximately in, a common line of feed, two or more feed-tables forming a continuo us line of feed arranged between adjacent stands of rolls and means for shifting the ends of the feed-tables adjacent to the rolls in the same or in opposite directions, substantially as set forth.

2. In a rolling-mill plant, the combination of two or more stands of rolls arranged in, or approximately in, a common line of feed, feedtables having reversible feed-rollers and forming a continuous line of feed arranged between adjacent stands of rolls, and mechanism for shifting the ends of the table adjacent to the rolls in the same orin opposite directions, substantially as set forth.

3. In a rolling-mill plant, the combination of two or more stands of rolls arranged in a common line of feed, one or more feed-tables forming a continuous line of feed arranged between adjacent sta-nds of rolls, means for shifting the ends of said tables adjacent to the rolls in the same or in opposite directions, feed-tables arranged at the ends of the line or train of rolls, and means for shifting the roll ends of the tables in the same or in opposite direct-ions, substantially set forth.

t. In a rolling-mill plant, the combination of two or more stands of rolls arranged in or approximately in a common line of feed, a feed-table having reversible feed-rollers arranged between adjacent stands of rolls and forming a continuous line of feed, and meehanism for shifting the ends of the table adjacent to the rolls in the same or opposite directions, substantially as set forth.

5. In a rolling-mill plant, the combination of two or more stands of rolls arranged vin a common line of feed, two or more feed-tables arranged between adjacent stands of rolls, feed-tables arranged at the ends of the line or train of rolls and mechanism for shifting the ends of the intermediate table or tables independently of each other, but simultane- 9o SIGMUND V.
